Abstract
The comparative study of Hunter-Schreger bands patterns has been done in reflected light and under the illumination of enamel surface by HeNe-laser beam. In the absence of laser illumination the exterior of bands depends on direction of incident light. Under enamel surface laser illumination the exterior of bands may coincide or not with the patterns revealed in reflected light. The present paper gives the explanation of this phenomenon on base of waveguide theory of light propagation in enamel prisms. No Hunter-Schreger bands were observed in hypermineralized enamel because the hypermineralization results in homogenization of structure and probably in disappearance of difference between values of refraction indices of prism and interprism spaces.
